The biggest company in the world just put a hardware engineer in charge

Every succession is an argument about what a company thinks it is. Apple made its argument on 1 September 2026, when John Ternus became chief executive and Tim Cook moved to executive chairman after fifteen years in the job.

Who got the job

Ternus joined Apple in 2001 and had been senior vice president of Hardware Engineering: the person responsible for the physical iPhone, iPad, Mac, Apple Watch and AirPods. Twenty-five years inside one company, all of them on the side of the business that has to be manufactured.

That is not the profile the last decade of business writing would have predicted. The received wisdom says a company facing a software problem hires a software answer, preferably from outside, preferably with a mandate to break things.

What Apple did instead

It promoted the person who makes the objects, and it did so on a schedule announced in public four and a half months in advance — the change was announced on 20 April and took effect on 1 September.

Cook does not leave. As executive chairman he keeps a defined remit that Apple describes as engaging with policymakers around the world — which is a way of saying the company decided its regulatory relationships were a job in themselves, not a thing a chief executive does between product reviews. Arthur Levinson, chairman for the past fifteen years, became lead independent director the same day.

The inheritance, in numbers

Under Cook, Apple went from a market value of about $350 billion to roughly $4 trillion. Revenue rose from $108 billion in FY2011 to $416 billion in FY2025. Services became a business of more than $100 billion on its own. The company added over 100,000 employees and now counts more than 2.5 billion active devices across 200-plus countries and territories.

Those are the numbers a successor is measured against, and they are the reason the safe-looking choice is not obviously the safe choice. A company that large does not get to grow by another order of magnitude; the next fifteen years will be judged on something other than the chart.

Why it is worth watching from here

Apple sells in more than two hundred countries and territories, which means this is one of the very few corporate decisions that lands in every market at once, including this one. Nothing changes for anyone buying a phone this week. What changes is who decides what the phone is in 2031.
